Definition of UV Ink

UV ink is a type of ink that does not require solvents, has fast drying speed, good gloss, bright colors, and is resistant to water, solvents, and wear. UV ink has become a relatively mature ink technology, with almost zero pollutant emissions. According to statistics, the annual production of UV ink is about 16000 tons in Japan, 18000 tons in Europe, and 19000 tons in North America. It should be noted that water-based UV ink in UV ink is a new research direction in the field of UV ink. Because the viscosity of prepolymers in ordinary UV inks is generally high, active diluents need to be added for dilution. The diluents used, acrylic compounds, have varying degrees of skin irritation and toxicity. Therefore, while developing low viscosity prepolymers and low toxicity diluents, another development direction is to study water-based UV inks, which use water and ethanol as diluents. Water based UV inks have been successfully developed and applied in some printing companies.
